### Description

The Belle II experiment is a substantial upgrade of the Belle detector and will operate on the SuperKEKB energy-asymmetric $e^+ e^-$ collider at KEK in Tuskuba, Japan. The accelerator successfully completed the first phase of commissioning in 2016 and the Belle II detector saw its first electron-positron collisions in April 2018. Belle II features a newly designed silicon vertex detector based on double-sided strip and DEPFET pixel detectors. A subset of the vertex detector was operated in 2018 to determine background conditions (Phase 2 operation); installation of the full detector was completed early in 2019 and the experiment started full data taking. This talk will report on the final arrangement of the Belle II silicon vertex detector with focus on silicon vertex detector setup, its data acquisition workflow, online and offline monitoring of detector conditions and data quality, design and use of diagnostic and reference plots, and integration with the software framework of Belle II.
